BUTTON-ATTACHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 544,528, dated August 13,1895.

Application filed September 17, 1894. Serial No. 523,298. (No model.)

To aZZ whom it may concern:

Be it known that I, CLYDE J. COLEMAN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Button-Attaching Machines; and I do hereby declare the following to be a full, clear,'and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to that type of button-attaching machines in which the stapleis threaded through the eye of the button and the staple placed in a feeding-chute with the button attached thereto and to be successively released during the continued operation of the machine and fed into the path of a clinching mechanism, by which the staple, with the button attached, is clinched or set upon the shoe-upper or other fabric; and the present improvement has for its object in the'main to provide a very simple and efficient mechanism for receiving the staple and the button attached thereto and efiectively holding and guiding the same in proper position to the fabric while the setting-plunger descends and drives such staple through the shoe upper or other fabric and clinches the staple therein. I attain such object by the construction and arrangement of parts illustrated in'the accompanying drawings, in which- Figure 1 is a side elevation, partly sectionized, of a button-attachin g machine constructed in accordance with my present invention; Fig. 2, a detail section of the same atlinemoc, Fig. 1; Fig. 3, a plan view of the magnetic support or holder detached, by which the staple and its button are held in the path of the setting-plunger and guided in proper position to the fabric while being driven and clinched in place in the shoe-upper or other article; Fig. 4, a front elevation of the same.

Similar numerals of reference indicatelike parts in the several views.

Referring to the drawings, 1 represents the main standard or head of the machine, having a lateral bracket 2, that supports the anvil or clinching-die 3 of the machine, and a lateral guide-arm 4, that guides the lower end of the setting-plunger 5.

6 is the operating rod or bar passing vertically down through the main head 1 and suitably guided therein, its lower end being connected as usual to a suitable operating-treadle, from which it receives a reciprocating movement, its upper end being provided with a lateral arm 7, to which the setting or clinch ing plunger is fixedly secured.

common to the present type of button-setting machines, and in their more detailed construction may follow the ordinary and most approved construction now in general use.

8 is the usual staple and button holding and feeding chute, by means of which the buttons are held suspended in series by means of their staples lying within the channel of said chute, as usual. his material to the presentinvention that the lower or discharge end of this button holding and feeding chute 8 be arranged in a vertical plane, as shown in Fig. 1, and in line with the staple-holding face of the magnetic holder hereinafter described, so that the staples with their attached buttons will be fed or directed down to said holder in a proper position for setting.

In the present invention the holder or support, by which the staple, with the attached button, is held and supported in the path of the setting-plunger, is in the form of a magnet 9, preferably of a horseshoe or rounded form, as shown, and preferably secured to the main frame in a horizontal position, with the polar ends 10 and 11 arranged in close proximity to each other, so as to form a narrow vertical space or throat 12, down which the shank of the button travels while the staple is held against the vertical faces of the polar ends of the magnet. The rear of such polar ends is cut away to form a vertical passage 13 to admit of the unobstructed passage of the button-head. As so arranged and combined the polar ends of the magnet arrest the staple, with its attached button, by magnetic attraction as the same leaves the feed ing-chute, and hold the same in proper position in the path of the clinching or setting plunger 5, and continue to hold the staple, 850., while it is driven downward into the shoeupper or other fabric to be clinched upon the anvil 3. r"

In the constructionillustrated in the drawings the magnet 9 is/attached in place by being bolted to the lower end of the vertical The parts so far described are usual and plate or member 14, that supports at its upper end the staple and button feeding chute 8. Any other means of attaching the magnet in place may, however, be used without depart ing from the spirit of my invention, and such attachment being either a rigid or movable one, as may be desired.

In order to automatically release the buttons and their carrying-staples that are carried in the upper end of the button-chute, so that they will descend or be fed one at a time and at each stroke of the machine, an automatic mechanism operating in the following manner may be employed: In this 15 and 16 are a pair of pawl-plates pivoted at some distance apart upon the stationary portion of the machine and having rearwardly-projecting extensions 17 and 18, that are in the path of an operating pin or tappet 19 on the reciprocating head 7 of the machine, so as to be alternately actuated by the same on its final up-and-down stroke. These pawl-plates are also provided with the individual teeth 20 and 21, that project into the interior of the staple and button chute 8 to engage and hold the button-staples contained therein against downward movement, and which teeth for the purpose of a proper feeding action will be arranged as follows: the tooth 20, of the upper pawl plate 15, a short distance below the tooth 21 of the lower pawl-plate 16, so that on the upper stroke of the cross-head or lateral arm 7 a staple and its attached button will, by the movement of the pawl 15, be released and permitted to descend onto the magnetic or other holder, so as to be in proper position to be set into the shoe-upper, the, on the next downstroke of the machine. In the completion of such downstroke of the machine the pawl 16 will be operated to release one of the superimposed series of staples and attached buttons and allowthe same to drop down against the lower tooth 20 ready for the next operation of the same to a release.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a button attaching machine, the combination of a driving plunger, a clinching anvil, an intermediate magnetic holder, and a feeding chute, the lower or delivery end of which is arranged in a vertical plane, the holding face of-such magnetic holder, being arranged in line with and directly beneath the delivery end of the feeding chute, to arrest and hold magnetically the descending button staple in the path of the driving plunger, and provided with a vertical passageway for the movement of the button shank during the operation of forcing the magnetically held button staple down upon the anvil, substantially as set forth.

2. In a button attaching machine, the com bination of a driving plunger, a clinching anvil, an intermediate magnetic holder, a feeding chute, the lower or delivery end of which is arranged in a vertical plane, and means for feeding the staples with their attached buttons singly to the magnetic holder, the holding face of such magnetic holder being arranged in line with and directly beneath the delivery end ofthe feeding chute, to arrest and hold magnetically the descending button staple in the path of the driving plunger, and provided with a vertical passageway for the movement of the button shank, during the operation of forcing the magnetically held button staple down upon the anvil, substantially as set forth.

3. In a button attaching machine, the combination of a driving plunger, a clinching anvil, an intermediate magnetic holder, and a feeding chute, the lower or delivery end of which is arranged in a vertical plane, the holding face of such magnetic holder being arranged in line with and directly beneath the delivery end of the feeding chute, to arrest andhold magnetically the descending button staple in the path of the driving plunger, such magnetic holder, being formed by a magnet, the polar ends of which are arranged in aseparated proximity and in a plane at right angles to the path of the driving plunger, to afford a passageway for the movement of the button shank, during the operation of forcing the magnetically held button staple down upon the anvil, substantially as set forth.

4. In a button attaching machine, the combination of a driving plunger, a clinching anvil, an intermediate magnetic holder, a feeding chute, the lower or delivery end of which is arranged in a vertical plane, and means for feeding the staples with their attached buttons singly to the magnetic holder, the holding face of such magnetic holder being arranged in line with and directly beneath the delivery end of the feeding chute, to arrest and hold magnetieallythe descending button staple in the path of the driving plunger, such magnetic holder'loeing formed by a magnet, the polar ends of which are arranged in a sep arated proximity and in a plane at right angles to the path of the driving plunger, to afford a passageway for the movement of the button shank, during the operation of forcing the magnetically held button staple down upon the anvil, substantially as set forth.

In testimony whereof witness my hand this 12th day of September, 1891.
